The time-frequency position of the data enables the control channels used by the sender and the receiver to be flexibly allocated on demand, improving the efficiency, performance and applicability of the wireless communication system.

In S110, the transmitting end determines the channel time-frequency position of the control channel related to the current state of the receiving end according to the identity identifier of the receiving end in the current state. Specifically, when the receiving end is in different states, the corresponding system will assign different IDs. For example, if the receiving end is a terminal device, that is, the user equipment, in a random access procedure, the ID assigned to the terminal may be an RA-RNTI or a TC-RNTI; for example, if the terminal has accessed the system in an RRC_IDLE state. The ID assigned to the terminal may be a C-RNTI.

For example, in combination with the cell level information, the cell level information may be an Evolved Cell Global Identifier. "ECGI"), cell identity (eNB ID & Cell ID, "ECI"), system information - System Information-Radio Network Temporary Identity (SI-RNTI), paging-wireless network temporary identity ( Paging-Radio Network Temporary Identity ("P-RNTI").

In the embodiment of the present invention, according to the ID in the current state of the receiving end, or in combination with other information, such as cell level information, the transmitting end may determine the channel time-frequency position of the control channel of the receiving end, and the time-frequency position of the channel may be relative. For a position of a certain time-frequency reference point, for example, as shown in FIG. 2, the channel time-frequency position may include a time offset and a frequency offset with respect to the time-frequency reference point, for example, the channel time-frequency position may be It is the A position and the B position in Fig. 2. Specifically, after determining the ID of the current state of the receiving end, the transmitting end may determine a channel time-frequency position relative to a certain time-frequency reference point according to a preset rule. Optionally, the preset rule may be a hash function, such as MD5 The hash function may also be a modulo function, or may be another function, processing the ID of the receiving end, or combining the ID of the receiving end with the sequence of other cells, thereby obtaining a channel relative to a certain time-frequency reference point. Time-frequency position.

Optionally, as an embodiment, for example, the UE ID of a terminal is 0x36ED (16-bit number), and the cell-level information is used, for example, the ECI of the cell is 28-bit number 0x 13432A01, and the preset rule may be determined according to the MD5 hash function. The frequency position, specifically, the UE ID and the cell ECI are ORed (XoR) to obtain the number "0x13431CEC", and the MD5 hash function checksum of the hexadecimal number is "692b3803ead63124a96d618bc62b7513", one method is to intercept any given Position two two-digit hexadecimal numbers and perform modulo 10 and modulo 50 operations. For example, the first two digits of “0x69”, that is, the decimal modulo 105 modulo 10 operation can be obtained according to a preset preset rule to obtain a time offset. t=5, taking the last two bits “0x13”, that is, the decimal 19 modulo 50 operation to obtain the frequency offset f=19, and the time-frequency offset corresponding to the control channel of the terminal is (t, f)=(5 , 19), that is, the channel time-frequency position. Optionally, the sending end may further determine the channel time-frequency position according to the ID of the receiving end according to other preset rules, such as other hash functions, or a function, etc., and the present invention is not limited thereto.

In the embodiment of the present invention, the sending end determines the channel time-frequency position according to the preset ID, or according to the ID of the receiving end, or combined with other information, and the time-frequency position should be inside the resource allocated by the cell where the receiving end is located (for the terminal-to-terminal In the direct communication scenario, the time-frequency location should be within the resources agreed by both parties to the communication). For example, if a system has a radio frame duration of 10 ms and is divided into 10 subframes of length 1 ms; the carrier width is 10 MHz, and the guard bands at both ends are divided into 50 radio resource blocks (RBs) having a size of 180 kHz. Then the time component t in the time-frequency offset should be 0-9, and the frequency component f should be 0-49, then the time-frequency position of the channel ranges from (0,0)≤(t,f) ≤ (9, 49).

In the embodiment of the present invention, the sending end determines the time-frequency position of the channel where the control channel is located according to the ID of the receiving end or combined with other information according to a preset rule. The preset rule may be preset in the sending end, and may be in multiple manners. The preset rule is sent to the receiving end, so that the receiving end can also determine the corresponding time-frequency position according to the preset rule, thereby determining the control channel of the receiving end. Specifically, for example, the transmitting base station may use a common channel, such as a broadcast channel of the base station, or the like; or in a terminal-to-terminal direct communication (D2D) scenario, the transmitting terminal may also use a common channel, such as a discovery channel of the transmitting terminal ( Discovery channel), etc., the sender notifies all the receiving ends, that is, the terminal, and each terminal receives the same preset rule. Optionally, the base station can pass only to a certain Dedicated one or more terminal-specific dedicated messages, such as a random access response message, an RRC connection setup response message, etc., to notify the one or more terminals, different terminals may use different preset rules to determine the time-frequency location; or at the terminal In the terminal direct communication (D2D) scenario, the signaling of the terminal at the transmitting end is transmitted to one or more selected receiving terminals, and the different receiving ends may use different preset rules. The embodiment of the present invention is not limited thereto.

Optionally, the sending end may also change the ID of the receiving end, or change the preset rule for calculating the time-frequency position by using the ID, and notify the receiving end by signaling, etc.; or the receiving end may also change its ID and connect by random. The inbound or outbound scheduling request or other message notification sender, the corresponding time-frequency location calculation will be modified at the next valid location.

In the embodiment of the present invention, the sending end determines the time-frequency position of the channel where the control channel is located according to the ID of the current state of the receiving end, or may also combine other information. Optionally, as shown in FIG. 2, the sending end may include Relatively to the time offset of a certain time-frequency reference point and the time-frequency position of the frequency offset, the time-frequency position of the channel where the control channel is located is directly determined, such as the A position and the B position shown in FIG. 2; optionally, The position of the index channel can also be directly determined according to the time offset and the frequency offset, that is, the A position and the B position shown in FIG. 2 are index channels, and then the index information indication is determined according to the index information of the index channel. The location of the channel is the time-frequency location of the channel on which the control channel is located, and the embodiment of the present invention is not limited thereto.

In the embodiment of the present invention, the channel time-frequency position is determined by ID or combined with other information. Alternatively, the control channel position may be directly determined, or the index channel position may be determined first, and the index channel or the control channel may exclusively occupy the position. Time-frequency resources, for example, if the time-frequency resources of the location are not allocated, they can be used directly; if they have been allocated to the data channel, they can be used by puncturing in the data channel, and can also be used with other channels (such as the following data) Channel) sharing time-frequency resources, for example, by means of code division, space division (either beamforming or using a spatial data stream, codeword or data layer), or directly superimposing and then performing interference cancellation to share time-frequency resources, and the present invention Not limited to this.

In S120, the transmitting end sends the data time-frequency position indication information, the size of the time-frequency resource occupied by the data, and the data modulation and coding mode to the receiving end through the control channel on the time-frequency position of the channel, and the data time-frequency position indication The information is used to indicate the time-frequency location of the data in which the data sent to the receiving end is located. Optionally, the sending end may send, by using the control channel, information related to the hybrid automatic repeat request (HARQ), such as redundancy version (RV) information, to the receiving end, and the embodiment of the present invention is not limited thereto.

Optionally, when the transmitting end determines the time-frequency position of the control channel or the index channel of the receiving end, if the transmitting end determines that at least two receiving ends have the same channel time-frequency position, the code-division multiplexing mode or space may be adopted. Multiplexing methods, such as beamforming, or using different spatial data streams or data layers, such as using codebook-based precoding different codewords to distinguish between different a terminal at a spatial location, or a method in which the transmitting end directly superimposes signals belonging to different receiving ends and performs interference cancellation at the receiving end, so that the control channel or the index channel of the at least two receiving ends share the same channel time-frequency position to transmit information, Embodiments of the invention are not limited thereto.

The location may be an absolute time-frequency location, which may be referred to as a physical resource unit (Physical Resource Unit (PRU)); or may be a time-frequency resource that is not involved in allocation (eg, resources for a common channel, Or a logical resource after the resource that is not used for reasons such as avoiding interference with neighboring cells, the logical resource may be referred to as a virtual resource unit (VRE). There is a specific mapping relationship between the PRU and the VRU in one or more cells (in the terminal direct communication scenario, the time-frequency resource pool of the sender). This mapping relationship may be consistent or inconsistent for all terminals in the cell. Or partially consistent. For the part of all the terminals in the cell, the sender base station (in the terminal-to-terminal direct communication scenario, ie, the sender terminal) can use the common channel to notify all the receivers, that is, the terminal; optionally, for the case of inconsistency to different terminals The base station (in the terminal-to-terminal direct communication scenario, that is, the sender terminal) may notify the one or more by using a dedicated message (eg, a random access response, an RRC connection setup response, etc.) that is valid only for one or more terminals. The terminal, the embodiment of the present invention is not limited thereto.

When the VRU is used in the two time-frequency positions, the transmitting end may determine the VRU corresponding to the PRU according to the mapping relationship between the PRU and the VRU, and send the VRU to the receiver, and the receiver may derive the exact relationship according to the mapping relationship between the PRU and the VRU. The physical time-frequency position is received and received.

Specifically, the mapping relationship between the PRU and the VRU can be as shown in FIG. 3. Sender base station (or The sender terminal in the terminal direct communication scenario may indicate the mapping relationship by using various methods, for example, sending a PRU number that does not participate in (or participate in) mapping according to a certain manner, as follows:

The rule and the irregular PRU are respectively transmitted, and the PRU of the rule can be encoded (for example, only the first PRU position, the frequency interval, the time interval, the number of rule PRUs, etc., but not the location where each PRU is located) is transmitted. To save transmission overhead, wherein, as shown in FIG. 3, the PRU of the rule herein refers to a PRU transmitted according to a fixed time interval, and conversely, the irregular PRU indicates a PRU whose transmission time interval is not fixed; in addition, optionally The rules or irregular PRUs transmitted here may be PRUs that are available for transmission, or PRUs that are not available for transmission.
